All of the above. I'll add on with some others that are necessarily "war" or my "favorite" but are in my collection and go hand in hand with war.....
Inglorious Bastards
The Pianist
Schindlers List
The Good German
Edit : Not sure this was mentioned but definitely one of my favs....the Pacific. Oh, and just saw Stalingrad.
Edit again: Should have waited before posting....Miracle at St Anna and Defiance
